NEJE software provides automatic low light. If you use laserGRBL and lightburn software to adjust the focus, you need to enter a command: M3 S1; and give a motion command, for example: G0 x10 y10 f1000; so that low light can be lit;

N40630 module: If it is mainly used for engraving, adjust the focus to a distance of 5mm below the light barrier; then slide the laser through a 5mm spacer to use a fixed focus method;

The cutting and focusing methods are as follows:


NOTE: The A40640 is an adjustable focus module. Guide image above is a guide for the best adjustment settings. You can use a flat-blade screwdriver to adjust the focus position.
